Problems solved by technology

[0002] The brightness range of high dynamic range video perceivable by human eyes is about 0.001-100000 cd / m2. Due to the lack of corresponding effective display mapping processing technology between ordinary display devices (generally about 1-100 levels), it usually shows as Complete or partial loss of image detail in bright areas and image detail in dark areas

Abstract

The invention relates to a liquid crystal display-field emission display (LCD-FED) double-screen structure high-dynamic display system which comprises an LCD panel and is characterized in that the LCD panel is arranged above an FED panel. An FED is an initiative shining type full-solidifying plane light source device and has the advantages of being high in luminance, even in screen display, capable of scanning, low in power dissipation, long in service life, light in weight, thin in thickness, environment-friendly, free of mercury pollution, rapid in response speed, wide in angle of view, capable of working in a wide temperature range and the like. Study on high-dynamic range video display aspects is developed based on an LCD-FED structure, characteristics of being high in luminance and capable of conducting high speed dynamic scanning are sufficiently used, one-sidedness on two aspects including arithmetic study and display performance is overcome, space-time continuity of display is mainly promoted, technological innovation results on aspects of double-screen display techniques are obtained, and the LCD-FED double-screen structure high-dynamic display system has important scientific and social meanings.

Description

technical field [0001] The invention relates to an adjustable backlight source of a liquid crystal display, in particular uses an FED as the backlight source, and the backlight source can increase the contrast of the display machine and reduce dynamic afterimages. Background technique [0002] The brightness range of high dynamic range video perceivable by human eyes is about 0.001-100000 cd / m2. Due to the lack of corresponding effective display mapping processing technology between ordinary display devices (generally about 1-100 levels), it usually shows as Image detail in bright areas and image detail in dark areas is completely or partially lost. In order to solve this problem, this patent proposes an LCD-FED (Field Emission Display, Field Emission Display) research scheme, with the LCD as the foreground screen and the FED as the backlight screen. FED is an active light-emitting fully solidified planar light source device with high brightness, uniform screen display, sca...
